“I am filing this complaint regarding Kia America's arbitrary denial of coverage for a suspected connecting-rod-bearing failure in my 2014 Kia Rio (85,000 miles). The vehicle exhibits classic symptoms of the Gamma 1.6L GDI defect: excessive oil consumption (bone-dry after ~1,200 miles post-January 2026 shop oil change), flashing CEL, and loud rod knock after oil starvation. Kia corporate denied all extended warranty/campaign relief on 03/18/2025, stating the powertrain warranty expired in 2019 and "no campaigns" apply. This is inconsistent and deceptive: -U.S. Litigation: Early complaints and law-firm summaries in In re: Hyundai and Kia Engine Litigation II (C.D. Cal., 8:18-cv-02223) and related MDL explicitly referenced 2012–2019 Kia Rios with 1.6L Gamma GDI for the exact defect (oil burn → bearing failure → seizure/fire risk). However, Kia negotiated to exclude Rios from the final E2 Class Vehicles list (see kiaengineclasssettlement.com FAQ #6), limiting relief to Souls and select others despite the identical engine family. -Canadian Precedent: The McKenzie Lake/Strosberg class action explicitly includes 2012–2017 Kia Rios with Gamma 1.6 GDI for the same…”
“The contact owned a 2014 Kia Rio. The contact stated that the vehicle was taken to a dealer where it was serviced under NHTSA Campaign Number: 23V652000 (Service Brakes, Hydraulic). After the recall remedy was completed, the dealer provided documentation indicating that engine rods #3 and #4 were failing and could soon cause the engine to explode if not immediately repaired. Approximately 2 weeks later while the daughter was driving at approximately 70 MPH, the vehicle began to decelerate and emit smoke from underneath the hood. The driver was able to coast to the side of the road and safely exit the vehicle as it caught on fire. The fire department arrived on the scene and extinguished the fire. A police report was filed and no injuries were reported. The vehicle was towed and deemed totaled since the fire consumed it. A dealer was contacted. The manufacturer was made aware of the failure and opened a case. The failure mileage was 133,223.”
“The contact owns a 2014 Kia Rio. The contact stated that the vehicle was consuming approximately 1/2 to 1 quart of oil per day. The air bag and check engine warning lights were illuminated. The vehicle was taken to an independent mechanic who informed the contact the catalytic convertor was not operating as designed. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 100,000.”
